Abstract
PURPOSE: A sodium salt of CMC, which has been treated with an aldehyde such as glyoxal, is added to mud to prepare a mud for civil engineering, e.g., for ground excavation that forms uniform suspension by stirring for a short time and has an appropriate viscosity.
CONSTITUTION: For example, a sodium salt of CMC is suspended in a solvent such as a water-alcohol mixture and a glyoxal solution in water or alcohol is added to the suspension. Then, the mixture is heated under stirring, filtered, dried and added to mud. As the above aldehyde, is used an aliphatic aldehyde, dialdehyde or aromatic aldehyde.
